had the same issue.. check below.
In the video, it is mentioned that we take all the 19 files (including from the drivers folder) and paste it in a new folder under WICED_SMART-SDK\APP\WICED_SENSE. You need to retain the driver\ subfolder while copying and the files within it as is..Don't copy just the files within as the makefile.mk is using the driver\<file_names>...
APP_SRC = wiced_sense.c drivers/l3gd20_driver.c drivers/hts221_driver.c drivers/lis3dsh_driver.c
APP_SRC += drivers/lps25h_driver.c drivers/lsm303d_driver.c
APP_SRC += ws_sec_upgrade_ota.c ws_upgrade.c rsa_pub.
I did the above and it worked with "WICED_SENSE-BCM920737TAG_Q32 download" as a Target Make.
Or you change the makefile and remove "drivers/".
Let me know if it worked..
Thank you so much. It worked ..
